I didn't hate it but it did feel odd.
The lock only bugs me when trying to access the scissors. It blocks my thumb.
I have never seen the need for a lock on any SAK. I have never owned a Wenger. When I purchased my first SAK years ago I bought a Victorinox because I thought it was better looking than a Wenger, still do. I applaud Victorinox for keeping the Wenger models alive but there is a reason why they went under. If I want a locking blade, I will buy another knife, not a SAK.
